(精华)2020年7月1日 ASP.NET Core 解决跨域问题(工具版)

Microsoft.AspNetCore.Cors public void ConfigureServices(IServiceCollection services) { #region 添加跨域 services.AddCors(options => { options.AddPolicy("any", builder => builder.AllowAnyOrigin() .WithMethods("GET", "POST", "HEAD", "PUT", "DELETE", "OPTIONS").AllowAnyHeader() ); }); #endregion } public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory) { #region 使用跨域配置 app.UseCors("any"); #endregion } //在控制器上加上如下代码 [EnableCors("any")]
